600 grams / m2 hot dip galvanizing
what is the recommended amount of hot dip galvanzing. is 600 grams per m2 is acceptable, too less, or over kill
the answer depends on the type service (near salt water, for example) and the expected lifetime. see this link at the american galvanizers association for the detailed information so you can make the decision based on these factors:
275 g/m2 is common hot dipped galvanizing. 600 is heavy and used for particularly corrosive environments. in canada, these are referred to as z275 and z600 respectively.
